What protocol must be supported by routers to use RA easy connect?

“My friends and I have Windows 7. I would like to help him with the Remote Assistance and when I click "Use Easy Connect", I get the message: "Easy Connect is not available " I suppose the problem is the ports blocked by my router ( Dlink DI-624) or the protocol doesn’t be supported by my routers. I want to ask what protocol does Microsoft Remote Assistance Easy Connect use? Thanks !”

Actually, the router must support the Peer Name Resolution Protocol if you are in an attempt to use Remote Assistance Easy Connect. If the Peer Name Resolution Protocol service is set Disabled or you don’t open the TCP port 3389, then the Remote Assistance Easy Connect will be not available or it will turn to gray out.

How to enable Peer Name Resolution Protocol and TCP port 3389

Now we know that Microsoft Remote Assistance Easy Connect protocol is Peer Name Resolution Protocol. If the TCP port 3389 is not being opened and the protocol is set Disabled, remote assistance can't be completed. Here in this part let’s learn how to enable Peer Name Resolution Protocol and TCP port 3389 so that we can use Remote Assistance Easy Connect smoothly.

▣ Enable Peer Name Resolution Protocol

Step 1. Press Win + R and then enter “services.msc” in the box, hit "OK".
